Basic Information about TeleService
TeleService V6.1 Service Software for SIMATIC S7 and C7
3-4 A5E00921336-01
3.3 Phone Networks, Modems and Data Throughput
TeleService is used to establish a remote connection to a remote plant via a phone
network. The online connection makes it possible to edit the dialed plant as usual
with STEP 7.
Phone Networks Which Can Be Used
TeleService can be used with digital networks (ISDN), analog networks and radio
networks (with GSM technology). The subsequent table shows the respective
transfer duration normalized to the transfer duration of the MPI board
(CP 5611 = 1x) and as a function of the set TS Adapter I/II:
Connection: With TS Adapter I
V5.0:
With TS Adapter I
V5.1/V5.2:
With TS Adapter II
V1.0:
Direct connection (COM, 19.2 Kbps) 8 x 8 x -
Direct connection (USB) - - 2.5 x
ISDN network (64 Kbps) 16 x 11 x 8 x
Analog network (28.8 Kbps) 32 x 14 x 11 x
Radio network (9.6 Kbps) 150 x 40 x 30 x
Limitations
Communication with the TS Adapter via the CAPI interface is not possible in case
of internal ISDN boards and PCMCIA boards, unless you are equipped with a
virtual COM interface of the modem manufacturer.
Modem Support
TeleService was implemented to be independent of the modem. This means that
all the common modems (Hayes-compatible/AT commands) which can be installed
in the Control Panel of Windows can also be used by TeleService.
Basic requirement is that a physical/virtual COM interface must exist. The choice of
the modem types is determined primarily by the existing hardware of the
programming device/personal computer and the phone network to be used.
A selection of the following modem types/media is supported:
• Modems (external modems at COM interface, internal modems and PCMCIA
boards),
• External ISDN adapter at the COM interface
• Internal ISDN adapter with virtual COM interface (for example, AVM CAPI port)
• External ISDN modems (ISDN adapter with integrated analog modem
functionality) at the COM interface
• Radio network modems with GSM technology, PCMCIA adapter board or data
